JOHN F. C. BENDT, OF BALTIMORE, MARYLAND.

AUTOMATIC-ALARM DRIP-PAN.

To all whom it may concern:

Be it known that I, JOHN F. C. BENDT, a citizen of the United States,residing at Baltimore city, State of Maryland, have invented certain newand useful Improvements in Automatic Alarm Drip Pans, of which thefollowing is a specification.

My invention relates to drip pans for use in connection withrefrigerators and the like, and has for its object to provide an alarm,and means for actuating the same when the water from the melted iceshould be decanted to prevent overflow.

With the foregoing object in view my invention consists in certain novelfeatures of construction, arrangement and combinations of parts whichwill be hereinafter described and pointed out in the claim.

Reference being had to the accompanying drawings, forming a part of thisspecification, Figure 1 is a sectional elevation on the line 11 of Fig;2 of my invention; Fig. 2 is a plan view of the same, the electricalconnections being diagrammatically shown, and Fig. 3 is a sectional Viewon line 33 of Fig. 1.

A indicates the body part of the pan provided with handles B and C, anddivided into compartments 1 and 2 by means of a partition 3, provided onthe compartment 1 is a suitable cover 4, secured thereon in any suitablemanner such as hinges indicated 5.

Provided on the cover is a contact plate 6, mounted upon which are apair of standards 7, between which is pivotally secured a rod or lever8, the rod being secured short one of its ends, the longer portion ofwhich projects partially across the compartment 2, and carries asuitable float 9, by means of a suspending rod 10, adjustably secured onthe rod 8, by means of a slide 11, and thumb screw 12, the purpose ofwhich will presently be explained.

Provided on the cover and located at a point under the end 13 of the rod8 is a contact plate 14, connected by a circuit wire 15, leading andconnected to an alarm 16, and from the alarm 16 another wire 17 connectswith a battery 18, located in the compartment 1, the battery 18 beingconnected by a circuit wire 19 to the contact plate 6.

Specification of Letters Patent.

Application filed January 16, 1911.

"Patented July 4, 1911.

Serial No. 602,775.

My device is operated as follows: The drip water upon accumulating inthe compartment 2 will gradually raise the float, which will in turnraise the longer end of the rod or lever 8, and cause the opposite end13 of the lever to descend. WVhen the danger point has been reached bythe drip water, the end 13 of the rod 8 will engage with the contactplate 14, thereby closing the circuit and sounding the alarm. lVhen thewater has been decanted from the compartment 2, the float 9 will fail toraise the rod 8, break the contact and stop the alarm.

By means of the slide 11 and the set screw 12, the float 9 may beextended farther across the compartment 2 at a predetermined pointdesired and the quantity of water in the compartment required to soundthe alarm regulated to meet the desired requirements.

Slight changes and alterations might be resorted to in the form andarrangements of the several parts herein described, without departingfrom the spirit and scope of my invention, hence I do not wish to limitmyself to the exactconstruction as herein set forth; but,

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is:

A drip pan of the character described, comprising two compartments oneof which is provided with a hinged cover, and means supported upon saidcover for detecting a predetermined height of water in said pan, saidmeans embodying two contact plates secured upon the top of said cover, alever pivoted upon one of said contact plates and adapted to engage theother plate, a float adjustably secured to said lever and depending intothe uncovered compartment, a battery and an alarm secured to theunderside of said cover, and circuit wires connecting said battery andalarm with said contact plates.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN F. C. BENDT.
